Video Description
Methods let you write code once and use it everywhere! This is how we build complex programs from simple, testable pieces.
What you'll learn: • Creating and calling methods • Method anatomy (access, return type, name, parameters) • Parameters for input • Return values for output • Method overloading • Optional parameters with default values • Named arguments for clarity • Pass by value vs reference (again!) • Method scope and local variables • Expression body methods • Best practices for method design
Key principles: • Single responsibility - one method, one job • Keep methods small (under 20-30 lines) • Meaningful verb names (CalculateTax, not Process) • Consistent parameter ordering
